noob here, sorry if a repost. I am extracting a string from a file, and end up with a line, something like: abcdefg:12345:67890:abcde:12345:abcde Let's say it's in a variable named testString the length of the values between the colons is not constant, but I want to save the number, as a string is fine, to a variable, between the 2nd and 3rd colons. so in this case I'd end up with my new variable, let's call it extractedNum, being 67890 . I assume I have to use sed but have never used it and trying to get my head around it... Can anyone help? Cheers On a side-note, I am using find to extract

I have a data like below: A:B:C:D and I want to replace the C with data (say, Z ) so that it may look like A:B:Z:D How can I do it? =SUBSTITUTE(A1,"C","Z") Although I wasn't clear on whether you wanted G or Z , you mentioned G but your example output shows Z . jrad If you have A:B:C:D in cell A1, then this works: =CONCATENATE(MID(A1, 1, SEARCH(":", MID(A1, SEARCH(":", A1) + 1, LEN(A1) - SEARCH(":", A1) + 1)) + SEARCH(":", A1)), "Z", MID(MID(MID(A1, SEARCH(":", A1) + 1, LEN(A1) - SEARCH(":", A1) + 1), SEARCH(":", MID(A1, SEARCH(":", A1) + 1, LEN(A1) - SEARCH(":", A1) + 1)) + 1, LEN(MID(A1,

I have a sat of matrices and I want to extract only a part of the matrix that satisfy a condition. For example: values of the 150x180 matrix goes from 0 to 2.80 and I only want those between 1.66 and 1.77 I want to keep the values within the rang in their original location in the original matrix and set the other to zero. can anybody help me please. Thank you You can use logical indexing. First, find A entries that do not satisfy your conditions. Next, using A(idx) change them to 0: % example matrix A = 2.8*rand(150, 180); % find entries meeting some criterion idx = A<1.66 | A>1.77; A(idx) = 0

I want to extract contents of title tag from html string. I have done some search but so far i am not able to find such code in VB/C# or PHP. Also this should work with both upper and lower case tags e.g. should work with both <title></title> and < TITLE></TITLE> . Thank you. You can use regular expressions for this but it's not completely error-proof. It'll do if you just want something simple though (in PHP): function get_title($html) { return preg_match('!<title>(.*?)</title>!i', $html, $matches) ? $matches[1] : ''; } Sounds like a job for a regular expression. This will depend on the HTML

I am using R for extracting text. The code below works well to extract the non-bold text from pdf but it ignores the bold part. Is there a way to extract both bold and non-bold text? news <-'http://www.frbe-kbsb.be/sites/manager/ICN/14-15/ind01.pdf' library(pdftools) library(tesseract) library(tiff) info <- pdf_info(news) numberOfPageInPdf <- as.numeric(info[2]) numberOfPageInPdf for (i in 1:numberOfPageInPdf){ bitmap <- pdf_render_page(news, page=i, dpi = 300, numeric = TRUE) file_name <- paste0("page", i, ".tiff") file_tiff <- tiff::writeTIFF(bitmap, file_name) out <- ocr(file_name) file_txt

I'm making an app for my school which people can check with if they've got a schedule change. All schedule changes are listed here: http://www.augustinianum.eu/roosterwijzigingen/14062012.pdf . I want to search that page for a keyword (the user's group, which is entered in an EditText). I've found out how to make the app check if the edittext matches a certain string, so now I only need to download all of the text on that page to a string. But the problem is that it's not a simple webpage, but a PDFpage. I've heard that you need a special pdf library or something to extract the text from the
